Do locusts come out of the ground?

"Locust" refers to both homopterans known also as "cicadas" and to orthopterans known also as "grasshoppers".

Cicadas spend almost their entire life underground sucking tree sap from the roots. They emerge for a few weeks of reproduction and die.

Grasshoppers lay their eggs in the ground and the nymphs emerge shortly after hatching and spend the rest of their life above ground eating leaves.
